Brackets / Double round robin
Double round robin brackets and schedules by team count
A double round robin plays every pairing twice, once on each side. That is n × (n − 1) games, so keep it to small fields. Pick your team count for the schedule.
The table shows games and rounds for each size.
| Teams | Games | Rounds | Bracket |
|---|---|---|---|
| 3 | 6 | 6 | 3-team double round robin |
| 4 | 12 | 6 | 4-team double round robin |
| 5 | 20 | 10 | 5-team double round robin |
| 6 | 30 | 10 | 6-team double round robin |
| 7 | 42 | 14 | 7-team double round robin |
| 8 | 56 | 14 | 8-team double round robin |
| 9 | 72 | 18 | 9-team double round robin |
| 10 | 90 | 18 | 10-team double round robin |
When to use it
A double round robin plays every pairing twice, once with each team listed first. It is the format for a league that wants a home-and-away season.
The games are n × (n − 1), so ten teams already play 90. Keep it to small leagues, and use a single round robin when the field is bigger.
A league of six plays 30 games over ten rounds of three, so each team plays ten games. Eight teams play 56 games over fourteen rounds.
Home and away only means something if the venues differ. For a single venue, a double round robin is just a longer season with the pairings repeated. For a league with two sites, check the home count on each team before you start.
Each size page below shows both halves, with the second half reversed, so you can print the full season as one sheet.
